Do you want to pay with paypal or btc?

Hi,

These look great, i will PM you for one right now.

nice work

thanks for informing us first, i appreciate it. I think it is a good idea, let me know the details when you get everything sorted. Chinese New Year holiday is over now so no problems with delays on our end. Message me anytime if you have any questions.

Hello,
I was pleased with my hub and was considering whether to try to gather interest over in the Scandinavian sub-forum in pooling our resources for a 6+ unit order to save on shipping and get the volume discount.

Felt it would be good form to ask you first before I solicited a purchase.
Naturally, I would organise everything on my end and you would deal only with me in terms of payment and shipping.

Does the 6% BTC discount apply to the grand total including shipping, or only on the hub cost itself (not shipping).

Thanks, voltage requested noted. Will PM you the tracking info once it is sent.

 I just took you up on the ebay second chance offer..  I need 110 volt usa. Paid via ebay-paypal.  this worked well as I am a bit short on BTC…  

Yes….
I know the issue is the shipping and the price.

I can work on the shipping by using surface delivery, and possibly switching steel to aluminum, but metal tooling is not cheap…

But I don't even think there would be enough interest in a kickstarter.

Yep that bitch is 20A clear……. and that's the constant current it can provide at 5v1
There is even room to slap in different PSU, but there is no need…

And yep I know they are not cheap…. if I could find a way to sell this stuff at $50USD there would be a massive market, that said , how many USB 2.0 hubs have we bought over the years… I have a massive box of them I use for spares….

I have a couple of other USB hub products in Metal cases I evaluated, but they fall down on the PSU, and by the time I costed a new case and integral PSU … they come out at about the same cost.


Since the Fury chips are highly dependent on the onboard regulators, the closer you can get to 5.X at the socket, the cleaner the regulation at the chip…

Once the supply at the socket comes down to 4.7-4.8 then the regulation goes on the buck convertor feeding the  Fury.

Seriously….. next time they used a buck convertor, they should have targeted one that could go as low 3-4v for it's supply rail…, very few devices give 5v at the USB socket…

This is why the 49 port hubs are dodgy…. you have the potential for 40-50A of current slopping around the tracks, ping ponging about at  MH bit rates…..
god only knows what all that inductance looks like on a double sided pcb…..
Plus the other issue is the 'sense wire' is too far away from the farthest USB connector when using the ATX PSU @5v

Weeeeeeeeee……

Ive read through the thread but what are the dimensions for this hub ?

rgdz,
bhai

Don't get me wrong…
It is possible to get a 49 port 'hub tree' or even greater…. but not like that.

I have a very nice design for a 20,40,60,80 but the problem is the cost,  to get decent manufacturing prices I would have to run 500-1,000 pcs
(yep I could EASILY manufacture myself… but end up contaminating my residence with Lead/antinomy/mercury compounds)(queue red neck with toaster oven)

Just how many customers would I have…?
No one in their right mind is going to be using USB sticks for that sort of mine setup, which would basically leave setups for manufacturing.

Yesterday I was watching CCTVn ,
which is like a China undercover reporting… Shock HORROR… they found government approved Plastic water pipe manufacturers using Medical waste and contaminated plastics for municipal water supply pipe…
Y…A….W….N…  they do EXACTLY the same with all the food products they manufacture for the Export market… toasters,water kettles, clip together food containers (which incidentally is WHY I NEVER buy such products.. all my shit is glass or stainless)

Unfortunately what most people what these days is the cheapest shit possible, even if they have to buy and replace it 10 times….

If there is such a curse as reincarnation, I want to come back as the dumbest banjo strumming MOFO on the planet, because Ignorance truly is bliss.
